Differential Fluid Flush


When was the last time your car got a differential fluid change? If you’re not sure, it might be time to check in with a professional and find out if you’re overdue. Topping off your fluids and keeping on top of your car’s fluid change schedule is one of the best ways to protect the overall health of your vehicle.

Keep reading below to find out more about why a differential fluid exchange is important for your car.


Differential fluid is an important lubricant for your vehicle. It is also referred to as “gear oil” because it lubricates your car’s differential, which is made up of gears, bearings, and the clutch. Essentially, your differential is the part of your engine that allows your car to turn, and differential oil is what keeps that system lubricated and running smoothly.

In appearance, differential fluid looks like a thicker version of engine oil. It is typically about 80 weight, as compared to the lighter weights that are common among engine oils. Differential fluid comes in both synthetic and non-synthetic varieties.

The location of the differential fluid system and the kind of oil that it requires varies between front-wheel, rear-wheel, and all-wheel drive vehicles.


You should check your car’s specifications to find the manufacturer’s recommendation for differential fluid changes. In general, it’s good to flush your differential fluid every 40,000 to 60,000 miles. If you’re not sure about the specific recommendation for your car, a professional mechanic can help you locate that information.
Signs that your car is overdue for a differential fluid exchange include difficulty turning or stiffness in your steering wheel. You might also hear grinding sounds when you turn corners or feel your car vibrate when you drive.
If you hear humming sounds coming from your engine, have a mechanic check your differential fluid. The humming could be the result of metal grinding on metal due to an under-lubricated differential. This should be addressed right away to prevent differential failure.


Lubrication keeps your engine running smoothly and prevents its metal parts from overheating or grinding on each other. Metal-on-metal friction can destroy gears and wear down other engine components, so it’s important to stay on top of your car’s fluid change schedule. A differential fluid change now can help you prevent costly problems down the road.
